# This is an example of using complex datatypes.
# It is not recommended to use directly.
# To use a similar datastruct please define a custom message with appropriate semantic meaning.

# The multiarray declares a generic multi-dimensional array of a
# particular data type.  Dimensions are ordered from outer most
# to inner most.
#
# Accessors should ALWAYS be written in terms of dimension stride
# and specified outer-most dimension first.
#
# multiarray(i,j,k) = data[data_offset + dim_stride[1]*i + dim_stride[2]*j + k]
#
# A standard, 3-channel 640x480 image with interleaved color channels
# would be specified as:
#
# dim[0].label  = "height"
# dim[0].size   = 480
# dim[0].stride = 3*640*480 = 921600  (note dim[0] stride is just size of image)
# dim[1].label  = "width"
# dim[1].size   = 640
# dim[1].stride = 3*640 = 1920
# dim[2].label  = "channel"
# dim[2].size   = 3
# dim[2].stride = 3
#
# multiarray(i,j,k) refers to the ith row, jth column, and kth channel.
